 I would vote for making the upgrade process short.

 upgrades causing problems.
 Actually given how complex WordPress core is, they're relatively simple.
 The number of search results on Google isn't a good way to gauge "issues"
 as WordPress now powers 23% of all websites roughly. There will be issues
 even if there wasn't an upgrade routine, simply because of things out of
 WordPress's control (like hosting issues, etc).

 this discussion the primary control?

 This is a far more complicated matter than a simple characterset upgrade.
 The release also fixed a pair of security issues, and solved some long
 standing table schema issues. The schema updates were discussed at length
 for several years before they happened, along with many people testing the
 numerous alpha (trunk), and formal beta and rc releases. The best way to
 get involved with helping with this, if you'd like, is to help test beta
 and release candidates. They are announced on make.wordpress.org when they
 are available.

 In the future, you should test upgrades for plugins, themes and WordPress
 core using a test install. Sean Davis wrote a great guide on why and how
